To all whom it may concern:

Be it known that Janse- HER, a citizen of the United States, resi ing at Houston, in the county of Harris and State of Texas, has invented certain new and useful Improvements in a Pneumatic Roller Gin, of which the following is a specifica- 'tion.

This invention relates to new and useful improvements in a pneumatic roller gin.

, One object of the invention is to provide a device of the character described, which is particularly designed for the purpose of ginning cotton.

Another object of the invention resides in the provision'of a device of the character described, which includes a fixed stripper blade and a rotatable drum co-acting therewith, said drum being arranged to carry the seed cotton into contact with said blade whereby the lint is stripped from the seed; all in combination with, a reciprocating stripper bar, which operates against the cotton and assists in the stripping operation and prevents the congestion of the cotton and seed against the blade.

A further feature of the invention resides in the provision. of reciprocating lingers which hold the cotton against the drum, and at the same time impart a reciprocating movement thereto, thereby preventing congestion and assisting in stripping the lint from the seed.

A still further feature the invention resides in the provision of means for pneumatically feeding the seed cotton to the gin and carrying the ginned cotton therefrom for delivery to the condenser.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1, is a front elevation of the gin.

Figure 2, is a rear view thereof, shown partially in section.

Figure 8, shows an enlarged fragmentary sectional view of the drum and co-acting blade, showing the stripper bar in elevated position.

Figure 9, is a similar view showing the stripper bar in lowered position, and

Figure 10, shows a plan view of the reand the means for operating the same.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to a supporting frame work having the aligned bearings 2, 3 and 4:, wherein the hollow shaft 5 rotates. Between the bearings 2 and 3, this shaft is enlarged forming the drum 6, which is perforated to permit the free inlet of air. Fixed on one end of the shaft 5 between the bearings 3 and l, is the pulley 7, through whichthe shaft and drum are rotated. I

Supported by the framework, behind the drum, is thetransverse flue pipe 8, through which an air current is induced by means of a suitable current generator, (not shown) and the ends of the hollow shaft 5 are connected with the pipe 8, through the branch pipes 9, 9, whose rear ends are tapped into the flue pipe 8, and'whose other ends are connected to the respective ends of the shaft- 5, by means of the connections 10, 10.

The gin is provided with hopper 11, through which the seed cotton may be fed to the drum 6, and said drum, rotating in the direction indicated by the arrow in Figure 6, carries the cotton against the fixedtransverse stripper bladelQ, This blade is lined to the support 13, in front of, and beneath, the drum 6, and said blade is arranged tangential with respect to the drum, its upper edge being beveled, at 142, to conform to the contour of the drum, and to form a stripping edge let, extending from end to end of the drum and arranged closely adjacent thereto. A vertically movable stripper bar 15 rests against the front side of the blade 12, and is provided at its ends with clamps 16, 16, through which it is fastened to the lift arms 17, 17. The lower ends of the arms 17 are attached to coil springs 18, 18, secured to adjustable brackets carried by theframework and the upper ends there of are adjustably attached to the respective cam levers 19,19, by means of adjusting bolts 20, 20, which pass through the respective slots 21, 21, in said levers, and are tapped into said arms. The forward ends of the levers 19-, 19, are hinged to the respective blocks 21, 2l,'which are seated in the grooves 22, 22, of the framework, and are secured therein by means of the bolts 23, 23. The lower ends of these bolts have the heads 24, 2 1, and they pass upwardly through the oblong slots 25,25, and through the blocks 21, 21, and their upper endsreceivethe nuts 26, 26. The blocks 21 are adjustable toward and from the drum 6, but are held in fixed position by the front and rear set screws 27 2?, and 28, 28. It is obvious that said blocks be adjusted in the grooves wherein they are seated by loosening the nuts 26, and by then suitably adjusting the set screws 27 and 28, and thereby the stripper bar 15 may, be adjusted for the purpose hereinafter set forth. The free ends of the cam levers have anti-friction bearings, which ride upon the eccentrics 29, 29, carried by the shaft 5, just. inside of the bearings 2 and 3, and said levers are alternately lifted by said eccentrics, and lowered by said pull springs 18, so asto reciprocate the stripper bar 15, up and down, through the arms 17, 17.

The drum 6 is rotated rapidly and carries the seed cotton against the edge 15 of the blade 12. The suction through the perfora tions of the exposed front of the drum holds the seed cotton closely against the front part of the drum and the seed are arrested, by the blade and the lint is pulledby the rapidly rotating drum, from the seed, held by the blade, the lint passing on around the drum between it and the blade. Slidably mounted in suitable bearings carried by the front part of the framework is a reciprocating cross bar 37, which carries the spaced fingers 38, which are arranged in front of the drum and decline toward the same. This bar has a beveled roller 39, which projects into the cam shaped groove 40, of the short transverse shaft 41. This shaft is rotatably mounted in suitable bearings car ried by the framework and is rotated from the feeder (not shown) and operates through the groove 40, and roller 39 to re eiproca-te the bar 37, and the fingers carried thereby. The ends of the fingers 38 are flattened on each side and they serve to hold the seed cotton against the drum and also by their lateral movement, prevent the congestion of the cotton against the drum and blade and assist in the operation of stripping the lint from. the seed. The freed seed drop through between the fingers 38, and fall onto the chute board 30, and pass thence to the conveyer 42, arranged under the gin and are carried by said conveyer to any desired place. The stripper bar has considerable range of movement and clears the edge of the blade 12, when it has reached the limit of its upward movement and is withdrawn below the blade edge when pulled downward by the pull springs 18, and the rapid reciprocation thereof against the seed causes a continuous turning of the seed against the drum, thereby exposing all sides of the seed to the drum and blade, with the result that all the lint is stripped from the seed and the congestion of the seed against the blade and drum is prevented. The suction through the perforations of the drum assisted by the fingers 38, holds the lint cotton, and the seed closely against the drum until the lint is all stripped. from the seed and the seed is then free to pass through the fingers 38, onto the chute board 30; p

The support is a hollow member whose ends are formed square in cross section and are held in correspondingly shaped openings 31, 31. in the ends of the framework, by means of the adjusting set screws 32, arranged as shown in Figure 3, and providing for the vertical and lateral adjustment thereof. The intermediate portion of the support is open underneath and the opposing side is arcuate in general contour and perforated and spaced from. the drum, and the admission of air therethrough, is controlled by a suitable gate valve 35, which is manipulated through the valve grip 36. A wide chute 33 leads from the support 13, and enters the fiue pipe 8, the front edge of the lower wall of the chute being adja cent said support and the upper wall thereof being spaced from the drum and being also spaced from the semi-cylindrical hood 34. which closely fits around the upper part of the drum. An inlet space is thus provided I between the hood and chute for the admission of auxiliary air into said chute.

As before stated,- a suction is created through the flue pipe 8, causing a current of air through the perforations of the exposed part of the drum and through the branch pipes 10, 10, and also through the perforations of the support 13, and. the chute 33.

The cotton fed through the hopper 11 is held against the front part of the periphery of the drum 6, and is freed of the seeds by the combined action of the bar, the stripper blade, and the reciprocating fingers, as explained, and passes between the blade and drum into. the chute 13. The admission of air through. the perforations of the support counteracts the force of. the suction through the branch pipes 10, 10,

and the current gradually, separates the fiber, relieving it of motes ancl'the like, and improving the staple and the current of auxiliary air entering the chute between the upper wall thereof and the (IlILHIl relieves the drum of the remaining lint adhering thereto which passes on out through the chute 83 to the flue pipe 8, by which it is delivered to the condenser. in case'any of the lint is drawn'through the perforations of the drum into the interior thereof, this will also pass out at the ends of the drum through the branch pipes 10, 10, into the flue pipe 8 for delivery as before stated.

As the blade and stripper bar become worn requiring adjustment to hold them in proper relation to the drum and to each other, they may be adjusted through the instrumentalities provided for that purpose, and hereinbefore described.

A number of gins of theclass described may be arranged in alignment, forming a battery, and be readily accommodated by the same flue pipe 8, and the same hopper 11,and all thus arranged to feed the same condenser, resulting in economy of space and convenience in arrangement.
